Huygens view of Titan's surface (colorized)

Huygens returned this photo after landing on Titan on January 14, 2005. It has been colorized based upon spectral data. The round objects in this image are pebbles and cobbles composed of ice. The surface is darker than originally expected, consisting of a mixture of water and hydrocarbon ice. There is also evidence of erosion at the base of these objects, indicating possible fluvial activity.
